Product Description:
Indramat’s KDA 3.1-100-3-LPI-W1 fuses compactness with high output, delivering a steady 3.1 kW to fuel intensive machining tasks. The controller features 100 Nm peak torque to tackle heavy cuts head-on, while the three-pole design evens out electromagnetic phases to slash torque ripple and promote fluid spindle motion. Built to endure, the drive with IP54 rating wards off dust and splashed liquids, protecting sensitive circuitry and a water-cooling circuit swiftly wicks away heat to stabilize winding temperatures.
The flange-mount setup locks the module firmly in place to avoid misalignment under stress, and W1-grade insulation in the windings guarantees prolonged electrical lifespan. Weighing roughly 22 kg, it strikes a balance between sturdy construction and manageable handling. Running on 400 V AC at 50/60 Hz, it slots smoothly into global power infrastructures. Controller’s feedback is crystal-clear via an incremental encoder, honing speed and position precision. With a 100 A continuous current rating, it powers without tripping, and its 300 V DC bus voltage underpins efficient inverter performance to curb energy losses.
Digital speed commands flow over a SERCOS interface for tight synchronization, while a heatsink blower delivers forced cooling and operates on a standard 220 VAC supply to keep everything running cool under pressure. The KDA 3.1-100-3-LPI-W1 from Bosch Rexroth Indramat company incorporates an auxiliary encoder input to support second motor feedback and provides an incremental encoder output interface for integration into control loops. Further, it features a high-torsional-stiffness design for minimal deformation under load and offers an extensive speed range that spans from low idling to high RPM for versatile machining.
Frequently Asked Questions about KDA 3.1-100-3-LPI-W1:
Q: What output capability does the KDA 3.1-100-3-LPI-W1 provide?
A: The unit delivers a rated output of 3.1 kW which sustains continuous torque under high-demand machining conditions and supports extended operational cycles.
Q: How does the maximum torque specification affect the KDA 3.1-100-3-LPI-W1’s performance?
A: Maximum torque of 100 Nm enables the drive to handle substantial cutting and feed forces which maximizes material removal efficiency and prevents torque-related stalls.
Q: Why are three poles used in the KDA 3.1-100-3-LPI-W1 motor design?
A: The inclusion of 3 poles balances magnetic flux distribution which reduces torque ripple and promotes smooth, vibration-free spindle rotation across varying speeds.
Q: What role does an IP54 protection class play in the KDA 3.1-100-3-LPI-W1?
A: IP54 classification in KDA 3.1-100-3-LPI-W1 resists dust entry and splash exposure which safeguards internal electronics and extends operational reliability in harsh environments.
Q: How does water-cooled cooling benefit the KDA 3.1-100-3-LPI-W1?
A: Water-cooled thermal management absorbs and removes heat rapidly which maintains consistent winding temperatures and prevents thermal degradation.
